Frost Heave of Irrigation Canals in Seasonal Frozen Regions
Advances in Civil Engineering, 2019 Soil frost heave acts as a driver of the emerged fracture in the concrete lining of irrigation canals and subsequent water leakage in seasonal frozen ground. A model test was carried out on the frost heave of a U-shaped canal with concrete lining.

Frost heave in colloidal soils [PDF]
, 2011 We develop a mathematical model of frost heave in colloidal soils. The theory accounts for heave and consolidation while not requiring a frozen fringe assumption.

Testing of a road structure for frost resistance using the curve of frost heaving intensity [PDF]
E3S Web of Conferences, 2020 The article considers the main provisions of the regulatory methodology for estimation the frost resistance of a road structure. The technique for determining the degree of soil heaving is assessed taking into that the standard for its determination was issued in 1990. The intensity of frost heaving and its curve are being discussed. The characteristic

Secondary frost heave in freezing soils [PDF]
, 1996 Frost heave describes the phenomenon whereby soil freezing causes upwards surface motion due to the action of capillary suction imbibing water from the unfrozen region below. The expansion of water on freezing is a small part of the overall surface heave

Basic Study on the Frost Heave Pressure of Rocks : Dependence of the Maximum Frost Heave Pressure on Temperature [PDF]
, 2011 In this study, we attempted to measure frost heave pressure, i.e., the pressure that develops in the heat-flow direction when rocks are subject to frost heave and ice lenses grow.

Evolution Patterns of Frost-Heaving Pressure with Partial Ponding in Cold Region Tunnels
Geofluids, 2022 The calculation of the frost-heaving pressure is one of the key issues in the frost-resistant design of tunnels in cold regions. To reveal the frost heave mechanism of partial ponding behind the tunnel linings, a three-dimensional geo-mechanical model ...
